After this happens enough times, there is enough cumulative damage that it doesn't recover, and then you have a dead Xbox...
Beefed-up cooling seems like a good idea.

Yeah I water cooled mine.But because the GPU/CPU never gets hot enough to trip the built in thermal sensor, the 360 never gives the fans more then 5v , so for alittle extra cooling i bypassed the transistor so it always runs @ 12 volts, but that is too loud so i reduced it to 9v.But as ive said i want the fans to run for atleast 15 minutes after the 360 is powered down, so i need to have the fans connected to the 5v standby source.I just dont know how to accomplish this without damaging the system.I dont want any currents form either source feeding back into each other.I need some kind of switch that can detect when power from one source is cut off, and then switch to the other source, then when power is detected, switch back to that source.
Maybe its overkill, but Id rather be safe then sorry.I have temp probes on the gpu,cpu and inside the case.I noticed that when i shut the system down the inside case temps start climbing up because the fans arent running anymore.When the fans are running, the inside case temps stay @ ambient temperature, but when the fans are off the temp climbs to the temps of the gpu,and cpu.Then drop equally with the gpu,and cpu.Id like to keep the inside case temps as low as possible.
